Be-it known that I, EDWARD C. Mamnr, a citizen of the United States, residing at Traverse City, in the county of Grand Traverse and .State of Michigan, have'invented: a new "and useful Incubator and Brooder, of which-the following is a specification.

This invention relates to improvements in a combined incubator andbro'oder.

The primary objectof the. invention is to provide an incubator and brooder of novel construction, and provided with unique means for heating and ventilating the incubation and broodingcompartments.

.With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in-the com bination' and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of theinvention;

In the drawings: Figure 1 is a vertical section. Fig. 2 is a horizontal section. Fig. 3 is a transverse section.

In the drawings, 10 designates a double walled case or cabinet which is mounted upon legs 11,; the cabinet having an upper incubation compartment or chamber A and a lower brooding or nursery compartment or chamber B havingair inlets in ltswalls. Egg trays 12 are supported slightly above the bottom of the incubation compartment, and the said bottom is provided with an opening at one end to establish' communication between the brooding compartment and super osed incubation compartment. An incline plate or apron 16 is secured to the end wall 15 of the cabinet below the opening between the said end wall and the bottom of the compartment A to permitthe chicks to descend into the compartment B, the compartment B having a door 17 at one side provided with a glass panel.

The compartments are ventilated by perforated outlet and inlet pipes 18 and 19, respectively. The outlet pipes or conduits 19 are disposed between the egg trays 12 and the bottom of the incubation compartment to carry 011' the foul air from directly below the trays, and the inlet pipes 18 are disposed at the top of the incubation comincandescent e ectric lights 26 and arranged within the brooding compartments are similar lights 27,Baid h'ghts' being partially incased by the lower shields 28, which prevent the heat-:- and. light: :fromthe lamps from being projected directly downward, the shields and lights being secured to the side walls of the cabinet. The respective lights 26 and 27 'are regulated by the electricthermostats 29 and 30, the thermostat 29 being positioned in the incubation com partment and the thermostat 30 in the brooding compartment. In this manner the heat in the two compartments is maintained at an even temperature.

The cloth diffusin diaphragm 32 is disosed between the lig ts 26, andthe egg tray.

he compartment above the diaphragm receives the heat, moisture and fresh air and evenly distributes the admixture within the egg 0 amber after it is filtered through the diaphragm. The roper moisture is roduced by the humi or 31, shown in my atent No. 964,442. g p I The end 15 of the cabinet or case adjoining the opening in the bottom of the incubation chamber, or the artition between the two chambers, is provi ed with doors 33 for the upper or incubation compartment to enable the trays to be readily inserted an Withdrawn, and to otherwise ermit access to be had into the incubation c amber.

It will be evident that the diffusing diaphragm 32 serves to diffuse the light, heat and humidified air in the upper portion of the incubation com artment, descending to the egg trays, the oul air being drawn off from below the egg? trays through the discharge or eduction pipes or conduits 18. It is also to be noted that the air rising from the brooding compartment will pass through the opening in the bottom of the incubation compartment and will then be drawn off through the discharge or eduction pipes 18. Both sets of pipes or heaters-26 and 27 may be in o ration at the same time, or either set of ights or heaters may be operated independent of the other set, whereby the com artments may be efiectively heated and ventllated.

What is claimed is 1. In an incubator, a case having a brooding chamber provided with air inlets, and a superimposed incubation chamber, the incubation chamber bottom having an opening at one end leading to the brooding chamber, an egg I tray supported slightly above the bottom of the incubation chamber, air inlet means leading to the upper portion of the incubation chamber, air eduction means leading from between the egg tray and incubation chamber bottom, and independent heating means within the brooding chamber and the upper portion of the incubation chamber.

2. In an incubator, a case having a brooding chamber provided with air inlets, and a superimposed incubation chamber, the in-" cubation chamber bottom having an open ing leading to the brooding chamber, an egg tray supported slightly above the incubation chamber bottom, a diifusing diaphragm between the top and bottom of the incubation chamber, inlet and outlet conduits above the said diaphragm andbetween the egg tray and incubatlon chamber 4 bottom, respectively, and havin their outer 3 ends directed downwardly an upwardly, respectively, and independent heaters above the said diaphragm and within thebrooding chamber. 2 g

In testimony that I claim the foregoing 3 as my own, I have hereto afiixed my, signature in the presence of two witnesses.
